Be careful with those political signs!

After moving to the Back Bay, I got rid of my car. Before, however, I refused to put any political bumper stickers on it. This is despite the fact that I’m crazy about politics, that I live and breathe for new election news, that each morning I wake up already thinking about Joe Biden or Sarah Palin or Ted Kennedy.

Putting a political bumper sticker on your car makes you a target to drivers of the opposite political persuasion. And while the chances of anything dangerous happening are low, you could still be cut off, tailgated or flipped off. I’d rather stay safe on the road.

If not, you’ll be the jerk who wouldn’t move out of the way on the subway in an Obama shirt or the moron who stood on the left side of the escalator with a McCain button.

And in that moment in this hypothetical situation, Obama supporters become assholes and McCain supporters become dumbasses.

This is why you need to be careful with political signs — especially the ones you make yourselves. Grammar and spelling come into play. They sure do in these circumstances:
